Battery-Gride,'{ofwhich the following ;isa specification, reference being had therein' tothe aceompanying'drawings. lo .Thisinvention relates tomachines formal;- ing secondry-batteryplates or grids which are formed'by spinningtbe surfacesvof the blank; plates .to form .therein concentric grooves .the metal -from'whichis vspun up; v15- forming concentric rings'raised above the su'rface of thefplate to receivefand hold the activelma'terial voifthe batteryg-and its object-is togprovide-a cheap; durable; 'andj-ecient Inachine Iforzthe purpose adapted toprepareany.-y

The spinning-tool N consists of a shank portion N', squared at one end to fit the socket K in the spindle-head AK and provided at the other end with a hollow head or cup N2, in to which cup are setthe tubular ring-shaped knives N3, `formed with a cutting lower end and which are spaced apart by the spacingrings N4,a transverse pin N5 being provided to hold the knives in place. The spindles of the row at one side of the plate are driven in a direction opposite to that of the spindles of i the rowat the opposite side of said plate, and each tool of one row is directly opposite and in line fwith the opposing tool of the other row,se that when' the tools "are moved into contact with the plate the tools have no tendency to tear, twist, or bend the plate, as the force of one counteracts the force of the other, and as said tools are moved equally toward each other the plate will not be bent laterally, but will be grooved to an equal depth on each side. The tools N are rotated quite rapidly, so that when they are forced Y gradually into contact with the plate the m th knives and no metal be cut from the plate, and by forming the tool of concentric tubular knives set into the cup and held in place therein in any suitable manner new or derent-sized `knives may be put in at any time with but little trouble or expense.

.Having thus fully described my invention, what l claim is 1. In a machine for'making battery-plates, i Y vertical rows of rotatable spinning-tools journaled in bearings on lopposite sides of the machine in axial line with each other, means for tions, separate means or moving said tools driving-the opposing ioV ls in opposite direcframe in' a'direction at rightt angles to the l movement of. the holder on oppositesides lof the holder, :a vertical series of spindle-heads formed with sockets at their opposite ends journaled in bearings in s'aid posts, spinningttal willbe spun up into the spaces between l tools fitting in the sockets in the adjacent ends of said heads, spindleshjournaled in the frame having a sliding engagement with the sockets in the-opposite ends of' said heads, gears fixed ony said spindles and means for moving said posts from and toward each other.

3. In a machine for making battery-plates the combination with the frame, of a plateholder longitudinally movable in the frame, vertical posts mounted in guides on opposite sides of the frame, spindle-heads journaled in' said posts, spinning-tools carried by the adjacent ends ot' said heads, rotatable spindles havinga sliding engagement with the opposite ends of said heads jonrnaled in the frame and means for simultaneously moving said posts from andltoward each other, comprising transverse shafts journaled in the frame and each provided with a( right and a left hand screw thread to engage screwthreadedopenings in theends of said posts on opposite sides of said holder, a bevel-gear on Vone end of each of said screw-shafts, a verti- 'means for actuating said screw-shafts.

4. In a machine for .making battery-plates, the combination with the frame, of a vertical plate-holder mounted in guides transversely of the frame, vertical posts mounted in guides on opposite sides of the holder and movable from and toward the holder, a vertical row of spindle-'heads carried by each of said posts, spinning-tools carried by the adjacent ends of saidheads, spindles having a sliding en gagement with said heads journaled in the frame and means for moving said holder at substantially right angles to the axes of said tools comprising a shaft journaled on' the frame and having a screw-'thread to engage a screw-threaded opening inthe holder.

5. In a machine for spinning battery-grids, a tool provided with an' alternating series'of concentric knives and spacing rings, and

means for detachably securing said knives and rings in place.

6. In a machine for spinning battery-grids, a tool formed with a shank portion having a squared end and an enlarged hollow head, a 'series of concentric ring-shaped knives, aseries of .spacing-rings interposed between said knives, and a transverse pin passing throgh apertures in said knives, rings and head lto secure said knives and rings within the head.

In testimony whereof I aix my signature in presence of two witnesses.
